The statement that is NOT true according to the cost-benefit approach of Environmental Ethics is "derived from Kantian ethics".

Here's why:

a. The cost-benefit approach does not take morality or ethics into account: This is true. The cost-benefit approach is primarily an economic concept that weighs the monetary costs and benefits of decisions, without necessarily considering moral or ethical implications.

b. Derived from Kantian ethics: This is false. Kantian ethics, named after philosopher Immanuel Kant, is a deontological moral theory that asserts that the morality of an action should be based on whether that action itself is right or wrong under a series of rules, rather than based on the consequences of the action. It is fundamentally different from the cost-benefit approach, which is consequentialist in nature and focuses on the outcomes of an action rather than the action itself.

c. Difficulty in accurately assessing costs and benefits: This is true. One of the main criticisms of the cost-benefit approach is that it can be difficult to accurately assess and quantify all the costs and benefits associated with a particular decision or action, especially when it comes to environmental issues.

d. An implicit suggestion that cost is an important issue: This is true. The very nature of the cost-benefit approach implies that cost is a significant factor to consider when making decisions.
